ionocraft

An example of such an "ionocraft" device, as they are popularly known.

A simple ionocraft derivative, also known as a lifter, can be easily constructed by anyone with a minimal amount of technical knowledge.

When the ionocraft is turned on, the corona wire becomes charged with high voltage, usually between 20 and 50 kV.

The air gap is simply that, a gap of free flowing air between the two electrodes that make up the structure of an ionocraft.

In its basic form, the ionocraft is able to produce forces great enough to lift about a gram of payload per watt, so its use is restricted to a tethered model.

Much like a rocket or a jet engine, can actually be much more thrust efficient than a jet engine, the force that an ionocraft generates is oriented consistently along its own axis, regardless of the surrounding gravitational field.

The ionocraft is a propulsion device based on ionic air propulsion that works without moving parts, flies silently, uses only electrical energy and is able to lift its own weight plus additional payload, with the future prospect of its power supply.

An ionocraft or ion-propelled aircraft, commonly known as a lifter or hexalifter, is an electrohydrodynamic (EHD) device (utilizing an electrical phenomenon known as the Biefeld-Brown effect) to produce thrust in the air, without requiring any combustion or moving parts.

As these neutral molecules are ejected from the ionocraft, there are, in agreement with Newton's Third Law of Motion, equal and opposite forces, so the ionocraft moves in the opposite direction with an equal force.
